Developing and improving dental prosthetics
The universal scholar Johann Wolfgang von Goethe once described the inner complexity of natural morphologies as follows: 'No living thing is one, it’s always many.' In the development of the new Vitapan Excell anterior tooth line, the aim was to biomimetically reproduce this organically grown form. The multi-layer structure, intended to correspond to the anatomy of natural teeth along with the laws of biology were consistently considered in its shaping and proportions. In the following, Eva Kerschensteiner, dental technician and a teeth/prosthetics product and process developer at Vita Zahnfabrik (Bad Säckingen, Germany), reports on the detailed and targeted development of the highly aesthetic Vitapan Excell in accordance with the patent of nature.

Meeting the demands of everyday laboratory use is what drove the development of Vitapan Excell. It was also important to us that the dental prosthetics teeth fulfil the wishes and needs of users. The development team therefore exchanged ideas with dental technicians all over the world. Consequently the biological original is painstakingly...
